HAY-PRESS.

SPECIFICATION forming part of Letters Patent No. 352,546, dated November16, 1886.

Application filed February 5; 1886. Serial Nov 190,919. (No model.) I I[0 all whom, it may concern;

' Beitknown that I, JOHN LA DOW, a citizen ofthe United States, residingat Trumansbu rg, in the county of Tompkins and State of New York, haveinvented certain new and useful Improvements in Perpetual Hay-Presses,of which the following is a specification, reference being had to theaccompanying drawings.

The present invention relates to improvements in perpetual hay-presses,-and it consists in such combinations of elements and arrangements ofparts as enable me to construct the apparatus almost entirely of wood.

The details will be fullyhereinafter set forth.

In the drawings, Figure 1 is a side elevation of a press constructedaccording to my invention. Fig. 2 is a sectional elevation thereof. Fig.3 is a top plan view, a portion of the walkingbeam being broken away tomore clearly show the devices by which it is operated. Fig. 4 is a planview, partly in section, taken on the line44 of Fig. 2. Fig. 5 is an endview. Fig.6 is a section on the line 6 6 of Fig. 2. Fig. 7 is a sectionon the line7 70f Fig. 2. Fig. 8 is a perspective view of the follower.

Similar letters denote like parts.

The friction-chamber A and the compression-chamber B, which constitutethe lower portion of the apparatus, are formed of four strong woodenbeams, A, extending the entire length of the machine and forming theprincipal support for the co-operating parts. The beams A are separatedabove and below at one end by the cross-pieces a, and the side pieces,

' a, to which they are secured by screw-bolts b.

The cross-pieces are recessed and arranged to allow of some adjustmentthrough the screwbolts referred to, and the apertures in the side piecesare elongated, as shown, by means of which the friction-chamber A may beenlarged or contracted both vertically and transversely, and theresistance'to the passage of the ma terial being compressed and theconsequent weight of the bale, adjusted as desired.

The chamber 'A is providedwith sides A which are suitably andpermanently secured to the vertical stay-pieces a, and with top andbottom boards, A which are similarly secured. The top board terminatesat the end of the friction-chamber, as also do the sides, but the bot vtom board extends rearward to the end of the com pression-cha mber,forming abottom therefor, and may be centrally slitted to allow theescape of dust and trash.

The follower G is reciprocatcd at the end of thecompression-chamber B,where it is supported upon metallic guides which, in the form of flangesO, are attached to the inner sides of the beam A. The follower isconstructed of a solid front piece or head, D, sides D, which said sidesare grooved at d, asshown. Metallic strips D extend rearwardly andlengthen the supports of the follower, resting upon the guides O. Hollowbosses d, formed with suitable side extensions, are securely bolted tothe the follower to the crank D, by which it is driven. Aconnecting-pin, d passes transversely through the end of the pitman andthrough the pivotplates and hollow bosses and into the wooden sidepieces D, making afirm and secure connection between the pitman andfollower. The crank-shaft D is mounted in suitablebearingsneartherearendoftheframe, which frame is re-enforced andstrengthened by vertical blocks or stays, d d inserted between the upperand lower timbers, A, and

carries the geared wheel D", which meshes with pinion D, and isconnected through geared wheel D with pinion D and the belt-wheel E,from which it will be readily understood how the necessary reciprocatingmotion is com- 8 5 municated to the pitman and follower during theoperation of the machine.

The sides of the compression-chamber are tightly closed by boards 6,which extend from the blocks 01* to the extremity of thefrictionchamber, being there securely held by the side pieces, a.

Extending upward from above the rearward position ofthe follower isafixed bulk-head, F,

and supported upon suitable horizontal supports is a condenser-boxformed ofthe sides ff, tail-board g, and end G. The box is reciprocatedat each movement of the follower, and the material therein contained isconcentrated between its end G and the head F.

Above the condenser-box and upon suitable supports is placed a hopper,H, provided with a bottom, preferably of thin sheet metal, under whichthe tail-board passes when the box moves back to receive itscharge,which is then pushed into it from the hopper. As the condensermoves forward to concentrate the charge,the tail-board cl oses the spacein front of the hopper and prevents the material from descending untilthe box is again in position to receive it. upper hopper'frame,andprovided at their in ner sides with guide-strips '5. between which ismounted the feeder-board J, thatis actuated by the walking-beam J,supported and operated as follows: A rock-frame, K, is pivoted upon onaxis, K, mounted in brackets Kinear the rear end of the main frame, andfurther secured by iron braces L, attached to the frametimbers, andthrough the upper end of which the said axis passes. Upon this axis ismounted a pair of upwardly-extending links or arms, k, which carry thewalking beam J, and,being pivotally mounted, permit the outer endthereof, together with the feeder to which said outer end is pivotallyconnected, to move ver' tically without the interposition of links orother mechanical expedients. The remainder of the axis is covered bypipe-sleeves, which allow of its being firmly secured in positionwithout cramping the supporting-frame. The forward extremity, 7c. of therockframe carries connecting-links 10 which are attached to thewalking-beam, and impart rapid and positive upward and then downwardmovement thereto and to the feeder J When the feederis in its elevatedposition, the lowest port-ion, K, of the rock-frame is in the path ofthe crank end of the pitman, which, striking it, throws it upward andthe walkingbeam and feeder downward. Projections or cams L are securedon either side of the frame K in the path of the cranks D, which willstrike them after the depression of the feeder, and forcingtherock-frame upward will quickly return it to its first position,bringing the lower end, k, again into the path of the pitman D. Thecondenser is moved by means of pitmen Z l, which are pivoted uponmetallic platesf, secured thereto, the pitmen being actuated byvibrating arms M, suitablypivoted to the main frame and connected to thepitman D by links m, thus giving the condenser a movement 00- incidingwith that of the follower, and which can be lengthened or shortened byaltering the point of connecting the links mto the vibrating arm M. Thecharge having been transferred from the hopper to the condenser, andthence by the feeder to the compression-chamber, and there compressedagainst the resistance of the accumulated charges in thefriction-chamber, is automatically secured in position by spring-dogs,which, being forced outward by the passing charge, immediately returnand take position behind it. while the follower is at the forward end ofits stroke.

i The side dogs, N, are pivoted in the spaces between the side and topand bottom pieces and binge upon suitable vertical bolts passingStandards I I are secured to the through the timbers. They are providedwith retractingsprings n, that are placed upon short bolts n,extendinglaterally through the support, and acting to limit the inward movementof the dogs.

Across the top of the compression-chamber is placed a spring-actuatedretaining-bar, O,

which is faced with sheet metal at its under side, and secured atitsends to arms 0, pivoted to the frame-timbers. The bar 0 is depressed bysuitable springs, P. The follower being notched at its sides to receivethe spring-dogs N, and the upper side of the compressionchamber beingopen, when the charge has been compressed the dogs and retaining-barspring into position and retain it until the operation is repeated and afresh charge takes its place. Follower-boards are placed in thecompressionchamber in the usual manner, and as the charges accumulateand are gradually forced along the friction-chamber toward the exit atits open end, the wires are inserted through the open sides and thegrooves in the followerboards, and the bales tied and then discharged inthe well-known manner.

Having described my invention, whatI claim 1s 1. In a hay-press,thecombihatiomwith suitable compressing and condensing chambers, of afollower, a crank and pitman for reciprocating thefollower, the pivotedrock-frame K, the lower portion of which, K is located in the path ofthe pitman and the upper portion of which is provided with cams L, thewalkingbeam J, the feeder J and suitable supports therefor, andconnections between the rockframe andwalking-beam,whereby the latter ispositively actuated .at each movement of the rock-frame, as set forth.
